materials design & process technology

Example of Materials Dept. Work

The mission of the Electro-Optic (EO) Materials and Process Technology Division is to advance the state-of-the-art in technologies used for the production, processing, and characterization of electronic, optical, and electro-optic materials. The Division fulfills this mission through:

  • Leading edge research in novel crystal materials and crystal growth technologies
  • Establishment of pilot scale process demonstration facilities and prototype fabrication capabilities
  • Education and training of students and industry workforce in EO technologies
  • Transfer of these DoD critical technologies into commercial production

 

Saphire Crystal

Research Areas Include:

  • Pilot scale bulk crystal growth of wide band gap semiconductors and high temperature piezoelectric materials
  • Bulk crystal growth process modeling
  • Thin film crystal growth; multifunctional integration
  • Advanced heat spreader materials, heat sink design, and finite element simulation
  • Prototype device fabrication for power electronics
  • Optics finishing, sub-surface damage assessment, and mitigation
